lM PROVEMENT IN EVA PORATlNG-PANS.
Specification forming part of Letters Patent No. 198,900, dated January 1, 1878; application filed October 13, 1877. V
To all whom it mcn concern:
Be it known that I, WILLIAM A. MORRL SON, of Frelighsburg, in the Province of Quebec and Dominion of Canada, have inventeda new and valuable Improvement in Heater and Sugar-Evaporator Combined; and I do hereby declare that the following is a full, clear, and exact description of theconstruction and operation of the same, reference being had to I der hot or cause to boil the fresh or cold sup-' ply of the same before it reaches the said pan, so that the entire superficies of the bottom of the pan may be utilized in causing the sap to be reduced to sirup.
The nature of the invention consists in combining, with an evaporating-pan, a pipe or system of communicating pipes adapted to be placed in. the pan above the sap, which, being raised to the boiling-point, will cause the sap in the pipes to be delivered to the pan in a heated or boiling condition, thereby greatly accelerating the formation of sirup, as will be hereinafter more fully explained. V
In the accompanying drawings, the letterA indicates an oblong rectangular metallic pan, having near one end a transverse partition, a,
provided with a gate or sap-valve. Both of the compartments thus formedare provided with spaced partitions c, forming labyrinthine channels,which delay the sap in its passage from the front end of the pan to the rear end thereof, and cause it, to be longer subjected to i the efiects of the heat of the furnace.
This evaporatin g-pan may be made of any desired size, and of any of the usual materials, or combinations thereofi B represents the subsidiary heater, composed of a number of communicating pipes, d, arranged side by side, and provided with supporting-legs, if I so elect. These pipes are preferably flat upon their lower faces, in order that as extended a heating-surface as possible" may be had-that is, they are preferably semicylindrical in cross-section but they may be round, oval, or square, if I'so elect. The connecting-pipes e are at alternate ends of the pipes (l, and are so arranged that the induct and educt ends of the subsidiary heater which they form are both at the front end of the pan A, when it is placed in the said pan with its flat side resting upon the ribs or partitions c of the larger compartment. The induct end of the heater B is provided with a funnel, G,
extending up above the level of the top of the pan, and the educt end with a discharge-spout, f, the upper edge of which is raised up above the level of the top of the said heater, so that when the sap is running the pipes d 0 may be always full. The spout f is preferably at an inclination, so that the sap may be discharged from it free from the heater, and in a thin stream.
' The operation of the apparatus is as follows:
The pan A is first filled with sap nearly up to the level of the tops or partitions c, and a fire built in the furnace under the same. The sap being raised to the boiling-point, the heater B is placed in position on the said partitions, with its funnel and spout at the front end 0f-the "said pan, and the liquid run from the, sap-vessel directly into the funnel 0, its quantity being regulated by a stop-cock, faucet, or other equivalent device in the pipe leading from the sap -reservoir into the said funnel.
B it is subjected to a very strong current of steamand radiated heat arising from the boiling sap in the pan, so that when it reaches the spout f it is raised nearly to a boilingpoint. Sometimesit is actually boiling, and falls into the front channel 9 of the pan in this condition.
As the sap passes through the branches of the heater By this means the sap is made to boil at the moment it falls into the channel of the pan next the front end, whereas by the employment of the pan alone it would not reach that temperature until it had passed through several of the said channels and had reached nearly to the middle portion of the said pan.
It is evident that the heater causes agreat saving in time and fuel, and greatly facilitates I the formation of sirup.
When the sap has passed through the channels in its serpentine course from the front to the rear end of the pan A, it has been boiled down to a sirup, and is drawn off in a constant stream by means of a spout or faucet.
I do not confine myself to the precise construction of the subsidiary heater hereinbefore described, as there are many variations thereof which I might employ discharging the same functions; nor do I confine myself to placing WILLIAM A. MORRISON.
